A red flag for a guy's room? Well, you know, if he's got frozen heads in the freezer, that's not like a good sign. You know, lots of equipment all around the house, like buzz saws, or like, you know, sanding machines. Maybe they got some citric acid with like a couple rubber containers, that's not a good sign. If the dude, you know, has like holes in the wall, or knives in the wall, or like bullet holes in the wall, that's not a good sign. Also, if he's just like...

a mattress, a shovel, some duct tape, and some chloroform. massive red flag.

Man, you know these girls want to just say, if he's breathing.

I would think Albania, perhaps Vietnam, or China, and this way you may display a red flag.

If he has a 200 kilogram bomb.
